As usually I used minimalistic approach. The footprint is 8,5 x 6". It seemed natural to mount the transformers on the outside and 1" acrylic plate was used for that purpose. Since finding forster bits or saws in 2 3/6 size was hard, I cut out the opening in 2 1/2 size and used neoprene gaskets to stabilise TX in the holes. This provides extra decoupling as well.
To make everything more interesting, I used aluminum plate between TX and two angles for front and rear panels. Spacing them away from acrylic base, provides more 3-dimentional look. Special bushings were used to mount those angles.

The knobs are from the original ML preamp. I don't think you can buy them. The ones I have I bought from a forum member. But I noticed a similar knobs in Bent Audio preamp, which is also a dist. for the transformers.
I tried few other knobs, but this one seems to be the best choice.
The switches are from ALCO. I had them in my bin for years and they seem to be good looking, gold plated. Also using toggles here instead of relays or rotary switches seems also to be more purist approach.
I already see some mistakes. First of all, I did a ground lift switch, but it seems that this feature is only good with balanced setup
.
Secondly, I would make source switching with separate toggles (left and right), so to avoid crosstalk and be able to switch both signal and grounds. I think I will redo it. Since the setup is so good I might also use Kimber RCA's.
I think phase switching is possible with that setup?

Speaking of ML, I think one of the ML series knobs (what a coincidence) from Kilo would look very good on it.
An externally hosted image should be here but it was not working when we last tested it.
Digi-Key's carrying the ML series now.
By the way, most excellent work! You really have a knack for taking basic materials (flats, angles, etc.) and putting them together so the result looks anything but basic.

The transformers are sourced from here:

Just imagine that 6 months ago I didn't have any idea who Stevens & Billington is. Today, thanks to this forum, I might say that those probably are the best match for inverted GC amp.
Peter,
we are witnessing an amazing transformation in your designs.
Design-wise it's something in between the Shanling tubeSACD, a CHORD and an Hovland.
What is the blue gasket between the trafos and the chassis?
Does your wife have anything to say about you putting spikey things on her good table?
